Chapter 14, Problem 14.5P

Interpretation Introduction

Interpretation:

The specific strength of 2090-T6 aluminum alloy and die cast 443-F aluminum alloy needs to be compered. On considering actual densities, whether the difference between the specific strengths increases or decreases needs to be explained.

Concept Introduction:

Magnesium alloys are made by mixing magnesium with other metals such as aluminum, zinc, manganese, silicon, copper, rare earth and zirconium. The degree of strengthening depends on the temper designation although magnesium alloys are not as strong as aluminum alloys, their specific strengths are comparable. The response of magnesium to strengthening mechanisms is relatively poor.
